Welding zvinoreva welding zvinhu pasi pezvakatsanangurwa mamiriro ekuvakwa kwenhengo zvinoenderana nezvinodiwa zvekugadzira, uye kugona kuzadzisa zvinodiwa zvebasa rakatemerwa.By welding zvinhu, welding, chikamu mhando uye kushandiswa zvinodiwa zvinokanganisa zvina zvinhu.

Low carbon steel welding
Nekuda kweiyo kabhoni yemukati-kabhoni simbi (semuenzaniso: kabhoni simbi pombi), manganese, silicon yemukati ishoma, saka kazhinji haizove neyakakomba welding inodzima nyama yakaoma kana matishu.Yakaderera kabhoni simbi weld majoini epurasitiki uye kukanganisa kuoma kwakanaka, welding, kazhinji pasina preheating, kudzora tembiricha uye kupisa pakati pematanho, uchishandisa post-weld kupisa kurapwa hakunatsiridze sangano, iyo yose maitiro haifanire kutora yakakosha welding process matanho, weldability.

Medium carbon steel welding
Carbon mass chikamu che 0.25% ~ 0.60% yepakati kabhoni simbi.Kana iyo yakawanda chikamu chekabhoni uye manganese yemukati inosvika 0.25% haina kukwira, yakanaka weldability.Nekuwedzera kwekabhoni yemukati, weldability zvishoma nezvishoma yakadzikira.Kana iyo kabhoni yemukati ingangoita 0.45%, nepo yakavakirwa payakapfava simbi welding process inoshandiswa kana iri munzvimbo inopisa yakakanganiswa inogona kuburitsa brittle martensite, iri nyore kutsemuka, kuti kugadzirwa kwekutonhora kutsemuka.Kana welding, kuwanda kwehwaro zvinhu zvakanyungudutswa mu weld, iyo weld kuitira kuti kabhoni yemukati iwedzere, kukurudzira kupisa kwekuputika mu weld, kunyanya kana kudzora kwakasimba kwekusvibiswa kwesarufa, zvakanyanya.Kutsemuka uku kunonyanya kunzwisiswa mugomba pakugoverwa kwekupisa mukutsemukira kweweld uye makwapa saka mitsetse yakamonyoroka yakanangana neiyo weld.

High carbon steel welding
Kana iyo yakakwira-kabhoni simbi kabhoni yemukati yakakura kupfuura 0.60%, kuomesa, welding crack senitivity mushure mekunge tsika yacho yakakura uye nekudaro husina kunaka weldability, haigone kushandiswa mukugadzira welded zvimiro.Inoda kunyanya kushandiswa mukugadzira kuoma kana kuputika kwezvikamu uye zvikamu, basa rekushongedza rinonyanya kugadzirisa kugadzirisa.Nekuda kwesimba rakanyanya kusimba kabhoni simbi kazhinji mu675MPa kana kupfuura, saka iyo yakajairwa electrode modhi E7015, E6015, inogona kusarudza E5016, E5015 electrode chimiro apo nhengo dzinokumbira zvakawanda.Mukuwedzera, tinogona kushandisa chrome-nickel austenitic simbi electrodes ye welding.Nekuda kweiyo yakakwira kabhoni simbi zvikamu kuitira kuti iwane kuomarara kwakanyanya uye kupfeka kusagadzikana, iyo pachayo inoiswa pasi pekupisa kupisa, welding inofanira kutangirwa nekuiisa kuti isungirwe.Inofanira kuitwa pamberi pekupisa preheat, tembiricha yepreheat inowanzopfuura 250 ~ 350 ℃, iyo welding process haifanirwe kunge yakaderera pane tembiricha yekubata layer pakati pekupisa kwekutanga.Weldment mushure mekunama kunoda kutonhora kutonhora uye nekukasira kupinda muchoto pa650 ℃ yekurerutsira kupisa kwekushushikana.
